The invention relates to a method for guiding from a remote control center
a vehicle towards a target object, said remote control center
communicating with the vehicle by means of a lagged communication
channel, comprising: At the vehicle: (a) Periodically capturing frame
images by a camera, assigning to each of said captured frames an
associated unique time stamp, and saving within a storage at the vehicle
full frame data or partial frame data of captured frames and their
associated time stamps; (b) For a plurality of saved frames, sending to
the control center via the lagged communication channel full frame data,
partial frame data or a combination thereof with the corresponding
associated time stamp for each sent frame so that approximate or exact
version of the sent frames can be reconstructed and displayed at the
control center; At the control center: (c) Receiving said frame data and
associated time stamps, sequentially reconstructing frame images from
each said sent full and/or partial frame data, and displaying the
reconstructed images on a display; (d) Upon marking by an operator at the
control center a point on a specific displayed frame, sending coordinates
indication relating to said marked point as appearing on said specific
frame or on a reference frame available at the control center, and the
time stamp associated with said specific or reference frame, as is the
case, to the vehicle; At the vehicle: (e) Receiving said coordinates
indication as marked and the sent frame time stamp; (f) Given the
coordinates indication and frame time stamp as received, fast forward
tracing said point or object coordinates from the said frame towards the
most recently available captured frame, thereby finding the coordinates
of the same point or object as appearing in the most recently available
captured frame; and (g) Providing the coordinates of the target point or
object within the most recently available captured frame, as found, to an
inner guidance sub-system of the vehicle, for enabling it to track said
object.
